Why Is My Bathroom Sink Clogged?
A slow draining sink does not happen for no reason. Below are the most common causes.
1. Hair Buildup
- Hair is the top cause of a bathroom sink clog.
- It wraps around the stopper and traps soap and dirt.
- Even short hair can build up over time.
Pro-Tip: Check under the stopper once a month. It takes 2 minutes and saves big trouble later.
2. Soap Scum and Toothpaste
- Soap does not fully wash away.
- It sticks to pipe walls and gets thick over time.
- Toothpaste also hardens inside pipes.
- This leads to a slow sink drain.
Pro-Tip: Run hot water for 30 seconds after brushing. It helps wash paste down.
3. Dirt and Small Items
- Rings, dirt, or small caps can fall in.
- Kids often drop things by mistake.
- These block water flow fast.
Pro-Tip: Use a drain cover. It costs little but stops big clogs.

You do not need fancy tools. Most fixes are simple.
Step 1: Remove the Stopper
- Pull it up and twist
- Or unscrew the rod under the sink
- Clean off all hair and gunk.
- Wash it with soap and warm water.
Pro-Tip: Take a photo before you remove parts. It helps when you put it back.
Step 2: Use Hot Water

The P-trap is the U-shape pipe under the sink.

When Should You Buy a New Drain or Sink?
